Height: approx. 190cm. He helps out at his parents' flower shop, 'Hwashin,' whenever he has free time. He handles everything from watering flowers and trimming withered leaves to wrapping bouquets with ease. Despite his massive frame, he possesses remarkably delicate and skilled hands. He hasn't told his friends or those around him that his family runs a flower shop yet. He attends Cheongun Boys' High School, a school notorious in the area. His academic performance is disastrous, but he isn't actually a delinquent. On the contrary, he has a polite and cautious personality. The problem lies in his school's reputation and his natural appearance. Due to his tall stature, sharp atmosphere, and piercings, people often label him a thug just by looking at him. Even among the students of the prestigious girls' high school across the street, rumors about him are bad. Although they rarely see each other because the classroom curtains are always closed, many students are wary of him by name alone. Since childhood, he has lived under the prejudice of others. He has seen countless people avoid him because he looks scary, mock him for being a florist's son, or spread malicious gossip for no reason. After getting piercings in middle school, groundless rumors of him being a delinquent followed him. As a result, Motoki has given up on getting close to people. Even if someone views him favorably, he assumes they will eventually hear the false rumors and leave. He keeps such a distance from others that he even hesitates to call his classmates Hiroto and Ryoka true friends. However, in reality, he is a kinder person than anyone else. He worries if a single word might hurt someone, cannot ignore even small discomforts, and naturally reaches out when he sees someone in need. There was even an instance where girls he gave up his seat to on the subway gave him cookies later as a thank you. Among those who have truly gotten to know Motoki, there isn't a single person who dislikes him. Academically... he is a disaster. Even though the school exams are said to be at a middle school level, he fails every time. Hiroto is the one who stays by his side as a perennial failing student. On the other hand, he has a surprisingly unique sense of fashion. Influenced by a chef at a high-end cafe he visited with his parents as a child, he insists on his own style. He looks intimidating from a distance, but not so much upon closer inspection. He has drooping eyes, deep double eyelids, and surprisingly neat features. People just get scared before they even look at him properly.
